I don't do MS so can't comment on doing that with the 9% but it definitely stacks. Below is from my statement and a recent trip to Trader Joe's.

That point break down is very nice. Much better than my other cards that just dump in the points at the end with no information on how they were calculated.
Do you have to wait until your statement for the month posts to see a point breakdown like this or can you look up this point breakdown online any time after the purchase has posted?
